Be it known that I, J OHN ROBERTS, of Greenfield, in the county ofHancock, and State of Indiana, have invented a new and usefulImprovement in Corn-Row Markers; and-I do hereby declare the followingto be a full, clear, and exact description of the same, reference beinghad to the accompanying drawing, which' is made a part of thisspeciiication.

My invention consists of a sullry-machine for laying oli or furrovvingcorn-,i 5rou1:r(l,7 preparatory to plant ing, of improved constructiom vIn the drawing- Figure 1 represents a plan view of my improved machine,and v Figure 2, a longitudinal section on the line :c-x,

form, consists of tw'o transverse pieces, or bars, A B, the former ofwhich constitutes the axletree, and three (more or less) longitudinalpieces, or bars O, a contin-v uation of the middle one of which may formthe tongue D, as shown. h

This frame is supported on wheels E E, and is adapted'to have anyrequired team attached in the ordinary manner, by means of the tongueI), a Whittletree, d, and hooks, or staples a d.

The customary' .drivers seat F is supported by means of a bracket, orsupport, G,attached to the axletree A, or other convenient part oftheframe.

The shovels, or markers H (one or more) are' pivpted in suitablemortises c, in the rear ends of the bars C of the frame, so asl toproject forward, as shown, and are connected at their lower ends to acommon bar, I,

'Ih'e frame proper of my machine, in the preferred,

by means of rods or links J passing through perforations c in said barsC.

Hinged to a standard, K, projecting from the middle bar C of the frame,is a treadle, or level', L, adapted vto project through and in front ofthe driver-s seat, and

connected by a yoke, t, or itsl equivalent, to the bar I, to whichtheshovels, or markers are attached, for the purpose of enabling theoperator to elevate or depress :the shovels, or' markers from his seat.

To enable these operations to be performed with equal facility from theground, a pair of handles, M, is attached to said bar I, and projectingrearwardly therefrom, is pivoted between a pair of standards, N,projecting upward from the rear bar B ot' the frame, by means of a rod,O, passing through saidstandards N, and through one of a series ofperforations, m, in each of the` handles M, the plurality of saidperforations allowing any desired adjustment of the handles.

`Having .thus described my nventiou,.

.What I claim as new therein, and desire to secure by VLetters Patent,is; Y
